GABTON-UPSETTING DEVICE.

To all whom it may concern."

Be it known that I, CARL BECKM'ANN, a citizen of the United States, anda resident of the city of New York borough of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedCarton-Upsetting Device, of which the following is a full, clear, andexact description.

This invention relates to a device for upsetting or opening cartonspreparatory to the receiving of the contents of the carton andconstituting an essential part of a cartoning machine.

The invention has for its general objects to provide a device of thecharacter referred to which is reliable and eficient in use, and sodesigned as to operate at a comparatively high speed.

A more specific object of the invention is the provision of a device ofsim lo and novel construction for the purpose 0 successively feedingcartons in flat form from a hopper, opening or upsetting the cartons toreceive its contents, and delivering the carton to a filling, closingand sealing mechanism, the opening or upsetting being accomplished by aplurality of fingers which, in closing, cause the carton to open andthen close on the other diagonal from that on which they are initiallyfolded or closed, and while held closed by the fingers, the carton istaken up by coacting rolls, which apply pressure in such a manner thatwhen the carton passes from the rolls it automatically opens out intoupset form, with the flaps open, so that the carton can be filled,closed and sealed by suitable mechanism.

With such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of arts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of theinvention and wherein similar characters of reference indicatecorresponding parts in all the views,

Figure 1 is a side view of the upsetting mechanism with a portion insection;

Application filed May 1, 1916. Serial No. 94,646.

Fig. 5 is a perspective view of an upset carton.

Referring to the drawing, A designates a hopper or magazine which iscomposed of suitably arranged upright members 1 in which cartons as theyare received in flat condition from the carton-making machine are placedin a pile, the cartons being ar ranged in a horizontal plane one on topof another. The pile of cartons B is supported on a horizontalreciprocatory plunger 2 which has a forward feeding portion 3 at a lowerlevel than the pile-supporting portion 4, and between these two portionsis a shoulder 5 which engages the rear edge of the lowermost carton whenthe follower plate is fully retracted, so that this shoulder will feedthe carton forwardly from under the hopper or magazine. The plunger orfollower 2 is operated by any suitable means and 1n timed relation tothe other parts of the upsetting mechanism. \Vhen a carton is fedforwardly a pair of fingers or pins 6 enter the ends of the carton,which latter slightly springs open, due to the resiliency of thematerial. These pins move inwardly and outwardly by suitable actuatingmeans and in proper relation to the movement of the plunger 2. Disposedforwardly of the plunger 2 aresets of pairs of fingers 7 fulcrumed on ahorizontal shaft 8, and these fingers swing upwardly toward each otherfrom the open position shown in Fig. 3 to the closed position shown inFig. 4, and thereby grip the carton B and cooperate with the restrainingfingers 6 to cause the carton to open from a flat horizontal position,and then close in a vertical position. This causes th breaking orflexing-of the carton at the folds b and b, givin the said folds thesame flexibility as the f0 ds 6 and 6 which are flexed or strained inthe folding of the carton by the carton making machine. Just prior tothe time the carton is flattened out by the closing of the jaws, as inFig. 4, the fingers 6 are withdrawn so that the carton can be fedupwardly between a pair of coacting rolls 9, between which the carton isforced during the last part of the flattening out movement. After thecarton passes between the rolls it automatically opens up into square orrectangular form and remains in this position, causing creases or foldsZ), b, 6 b of the same tension or flexibility. The fingers 7 are openedand closed by a lazy tongs arrangement 10 receiving motion from areciprocatory rod or bar 11 which Operates in timed relation to theplunger 2 and the holding fingers 6. are set up or opened, are fedprogressively to the right by a reciprocatory feeder in the form of athe left roll 9. This bar is supported at each end by an arm 13 which isfastened to a horizontal reciprocatorylink 14 actuated by an oscillatinglever 15. The feeder bar 12 makes a-stroke exceeding-the width of theupset carton, so that each time a carton is upset it is fed forwardly tomake place for the next carton. In this manner the cartons aresuccessively fed to the filling, closing and sealing mechanisms of acartoning machine.

From the foregoingdescription taken in connection with the accompanyingdrawings, the advantages of the construction and method 'of operationwill be readily understood by those skilled in the art to which theinvention appertains, and while I have de scribed the principle ofoperation, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes may be made when desired asfall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A carton upsetting device comprising means for feeding a flat, foldedcarton, fingers movable into and out of the ends of the folded carton,and fingers movable toward each other and arranged to engage externallythe carton at its front and rear folded edges and apply pressure to openand fold the carton flat on its other folds. v

2. A carton upsetting device comp-rising means for feeding a flat,folded carton, fingers movable into and out of the ends of the foldedcarton, fingers movable toward each other and arranged to engageexternally the carton at its front and rear folded edges and applypressure to open and fold the carton fiat on its other folds and in aplane at right-angles to the plane of the initial feeding movement thecarton, and rotating rolls between which the carton passes from thelast-mentioned fingers, whereby the car ton will automatically open upin square or rectangular form after passing through the rolls.

3. A carton upsetting device comprising means for feeding a fiat foldedcarton,

means for gripping the carton and progressively opening and folding thesame fiat on the other diagonal from that on which. it is The cartons,after they bar 12 normally disposed above initially folded, and rotatingrolls between I which the carton passes to cause all the folds to havethe same tension, whereby the carton will automatically open in squareor rectangular form after passing the rolls, the axes of the rolls lyingin a plane parallel to the plane of the initial feeding movement of thecarton.

4. An upsetting device comprising means for feeding a fiat folded cartonin its own plane, fingers movable toward each other and into theopposite ends of the carton, swinglng vfingers arranged to en age theedges of the flat cartons while the rst-mentioned fingers are engagedtherewith, whereby the carton is folded flat in a plane at right-anglesto its initial plane, and rolls arranged to receive the carton andconvey it away from the last-mentioned fingers, the axis on which theswinging fingers swing lying in a plane passing between the'rolls and inwhich the first-mentioned fingers lie.

5. A carton upsetting device comprising sets of swinging fingers whichmove open and closed, means for feeding a carton to the fingers when inopen position and holding the cartons centrally with respect to thefingers, means for moving the fingers toward each other while engagedwith the opposite folded edges of the carton to progressively open andfold the carton on the other opposite folds, and rolls arranged adjacentthe fingers in such position carton will automatically pass to the rollsas the fingers close 'on the carton.
